We already know from the first clip that Scarlett Johansson has some serious stunt work in "Marvel's The Avengers" — and rightfully so! Her character Natalie Romanoff, better known as Black Widow, is an undercover S.H.I.E.L.D. agent, and what kind of spy would she be if she didn't kick some butt?

When MTV News caught up with the actress at the red-carpet premiere of the film on Wednesday, we asked her which stunt sequence in the film she was most proud of mastering, and her answer almost turned into a spoiler reveal!

"The stunt sequence that I've been the most proud of is probably my fight with..." Johansson stopped abruptly. "Actually, I don't know if I can say!"

She looks at someone off camera and asks, "Can I say? I don't know if I can."

When we asked her if it's Loki (Tom Hiddleston), Johansson replied, "No," and her eyes became playfully shifty as she continued, "All I can say is that I had to fight someone else in this film, and they beat the crap out of me in stunt rehearsals. I have to say I could not believe it."

If it's not Loki, who could she be talking about? One of Joss Whedon's mysterious aliens, perhaps? All we know right now is that whoever he — or quite possibly she — is, they have some bigger muscles than Black Widow.

"I was like, 'Can you hold it back, OK? You know, I'm trying to work it out here. I've got smaller muscles than you,' " Johansson said. "I was dragged across the [floor]. When we finally finished [filming] that scene I was just happy to be alive."

The starlet also told MTV News which Avenger got roughed up the most. "We all took a pretty big beating," she said. "I would have to say either [Black] Widow or Hawkeye (Jeremy Renner). We're on the ground so we're fighting hand-to-hand and it hurts."

Considering Johansson was "just happy to be alive," we're putting our money on Black Widow.

"Marvel's The Avengers" hits theaters May 4 and experts are already predicting a massively strong opening weekend. Deadline reports a box office estimate of $125 million plus, which would make it the biggest non-sequel opening for Marvel. Tickets for the midnight release are already selling out fast.
